Almost from the start of SARS-CoV-2’s rampage around the globe, researchers and epidemiologists warned that it appeared to behave differently than known viruses, particularly seasonal flu. That included not only COVID-19’s general contagiousness compared to flu viruses, but also its ability to cause clotting problems in the veins and arteries, result in loss of smell and/or taste, and even lead to a rare multisystem inflammatory syndrome in children.
That message was taken more or less seriously, depending on geography and, often, politics. But as a new study makes clear, the warnings have proved darkly prophetic.
